Steven E. Koonin was the guest of Green Light, the podcast series of Climate Policy Institute.

Dr. Koonin is a physicist by training, professor of the NYU in climate science and energy, as well as author of the most recent release of MCC press, Unsettled. The consensual and debated elements of climate science, and the difficulties of reliable forecasting have been discussed, as well as whether the professor is in fact a climate denier as many claim.
